me state very clearly that the united states government had absolutely nothing to do with this video. we absolutely reject its content and message. >> reporter: secretary of state hillary clinton rejected the video but called upon governments to stop the violence resulting from it. >> any responsible leader should be standing up now and drawing that line. >> reporter: clinton's words came less than a day after u.s. ambassador to libya chris stevens and three others were killed by the violence. >> no act of violence shakes the resolve of the united states of america. >> reporter: the u.s. is sending two warships to libya in case they're needed, as the government tries to figure out if the attack was planned. u.s. intelligence officials believe it is very unlikely it is al-qaeda behind the attack. there are some in libya showing support for the slain ambassador but those signs of peace could be overshadowings by violence, for clouds who believe a video speaks not just for itself but for a country. >>> we have more details now about the youtube video that prompted some of that violence.
